# NousResearch/hermes-agent · MTP models spilling lose large prefill microbatch setting

- #137685: \[Bug\]: MTP models too large to fit the card never get the large prefill microbatch — child launches with no -b/-ub (engine default 512)
- PR #137689: fix(local-runtime): retain MTP prefill when spilling
- PR #141542: fix(local-runtime): an MTP model that spills in both postures keeps the large prefill microbatch

These items concern local-runtime handling of MTP models that are too large for the card and spill. One reports that the child process launches without -b/-ub flags (falling back to the engine default of 512), and the two fix-titled items appear to address retaining the large prefill microbatch in that case.
